How closely should I follow expiration dates on meds? Like Zyrtec (cetirizine) I found an unopened bottle but it expired about 6 months ago. Can I still use it?

In brief: Too long

six month is too long,i do not think there is any harm of taking it, but they will be no benefit, if it was few days up to a month i mught have defferent opinion six month is too long.
buy a new one.
